Cisco's industry-standard Gigabit Interface Converter (GBIC) is a hot-swappable input/output device that plugs into a Gigabit Ethernet port/slot, linking the port with the fiber-optic network. GBICs can be used and interchanged on a wide variety of Cisco products and can be intermixed in combinations of IEEE 802.3z- compliant 1000BaseSX, 1000BaseLX/LH, or 1000BaseZX interfaces on a port-by-port basis. Furthermore, Cisco is offering a 1000BaseLX/LH interface that is fully compliant with the IEEE 802.3z 1000BaseLX standard, but has the ability to go up to 10 km over single-mode fiber, 5 km further than garden-variety 1000BaseLX interfaces. As additional capabilities are developed, these modules make it easy to upgrade to the latest interface technology, maximizing investment protection.
The WS-G5486, 1000BaseLX/LH interfaces fully comply with the IEEE 802.3z 1000BaseLX standard. However, their higher optical quality allows them to reach 10 km over single-mode fiber (SMF) versus the 5 km specified in the standard.

Super Physical Contact with a 20 micron radius
Mode-conditioning patch cord (CAB-GELX-625 or equivalent) is required. Using an ordinary patch cord with MMF, 1000BASE-LX/LH GBICs, and a short link distance (10s of meters) can cause transceiver saturation resulting in an elevated bit error rate (BER). In addition, when using the Cisco 1000BASE-LX/LH GBIC with 62.5-micron diameter MMF, you must install a mode-conditioning patch cord between the GBIC and the MMF cable on both the transmit and receive ends of the link. The mode-conditioning patch cord is required for link distances greater than 984 feet (300 m).
